Here we go: the Molecular Systems Biology blog is launched, at last! I hope you will like it and react to it. Rather than providing theoretical goals or formal definitions, I finally decided to leave online some entries I posted prior to the launch, in order to give a flavor of the scope and style of this blog. Let's see how it will evolve, depending also on your feedback and suggestions.

I would also like to take the opportunity to warmly thank Pedro Beltrao (Public Rambling) for his invaluable help setting up the blog.

Welcome again and, please enter, the door is open!
